Are excuses for academic parties getting thinner or is it just me?

(arXiv, physics.ed-ph): Why every observatory needs a disco ball

"We tried on a number of occasions to observe different phases of the Moon using disco balls. We were successful with the full moon on 2022 December 7 [...]"

"During the period March-May 2023 we tested a portable disco ball as part of a permanent exhibition at a university observatory, receiving visitors in groups of all ages. [...]"

I mean: just send out invites like normal people darn it! :P

(Sorry for the thin joke. If nothing else the paper gets a little publicity. Whether that's merited I'll leave to you to decide.)

EDIT: Oh, this should of course have gone in the "Lame Jokes" thread. Feel free to move it. My bad.

Commercial disco balls provide a safe, effective and instructive way of observing the Sun. We explore the optics of solar projections with disco balls, and find that while sunspot observations are challenging, the solar disk and its changes during eclipses are easy and fun to observe. We explore the disco ball's potential for observing the moon and other bright astronomical phenomena.

A clever topic and well if not completely serious, I agree, a little light publicity on the subject may not be a bad thing.
